The three main branches of social science are anthropology, psychology and sociology. They all study human behavior. Anthropology is ultimately the study of culture:… the social science discipline that examines the development of the human species and human cultures throughout the world...tends to study groups in totality. Psychology is ultimately the study of human behavior: the social science discipline that examines people's feelings, thoughts, and personality development-focuses on the individual and processes internal to the individual. Sociology is ultimately the study of society: the social science discipline that looks at the development and structure of human society and how it works-examines the effects of society and group membership on human behavior. Additional Definitions: Anthropology (cultural customs and rituals): behaviors of groups and institutions, behavior of individuals within a group. Sociology (group dynamics, roles, rules and institutions): behavior of groups and institutions, behaviors of individuals. Psychology (personality development): behavior of individuals within groups, behaviors of individuals.

These are the branches of plant sciences: 1.Morphology is the branch of science deals with Description of different plant organs (two parts) (Fundamental prerequis…ite for classification of plants) 2.

The branches of earth science are so many and they have various roles. Some of them include geology which deals with land formations, oceanology which deals with oceans, m…eteorology which deal with weather and climate and so many more.

It is difficult to know what "the other sciences" might be when we don't know what science you are starting off with. But all sciences are characterized by a methodology--the …scientific method--which involves formulating a hypothesis and then trying by means of experiments to disprove it. If the hypothesis proves difficult to disprove, then we have more confidence in it. Among the sciences are Biology (the study of living things), Chemistry (the study of the properties of substances), Physics (the study of physical objects), Astronomy (the study of extraterrestrial objects), Anatomy (the study of the human body). Anatomy can be considered to be a branch of Biology, as can Zoology (the study of animals) and Botany (the study of plants). Chemistry can be divided into Organic Chemistry (the study of substances produced by living things) and Inorganic Chemistry (the study of substances not produced by living things). A number of disciplines apply the scientific method to human behaviour, and these are called the bevioural or social sciences. Among the foremost of these are Psychology (the study of mental phenomena) and Sociology (the study of human group behaviour).
